The Base Tech II Base Repeater is comprised of separate modules all housed within one 2RU equipment cabinet. The receiver, transmitter, and PA unit are each enclosed within their own die-cast housing. Each one is then mounted directly on the large upper heatsink. A microprocessor-controlled interface module controls the channel selection, LCD Display, timers, interfaces, and signaling features. The RF power output is 25 — 50/ 60 watts or 50 — 100/ 110 watts on a continuous duty basis. The CTCSS module supports all EIA tones. All tones and different encode and decode tones can be set on a per channel basis during radio programming. Attention The antenna(s) used for this transmitter must be fixed-mounted on outdoor permanent structures with a separation distance of at least 6 meters from all persons during normal operation. The peak conducted output power at each antenna terminal must not exceed 250 Watts and the peak radiated output power must not exceed 1000 Watts EIPR. Users and installers must ensure that FCC requirements for satisfying RF exposure compliance are met. (See FCC Rules Part 1, Sections 1307 and 1310) Features o Simplex or two frequency Duplex operation o EEPROM programmable with a PC com…

Midland Radio 71-3200A/B VHF Base Tech II 7.0 ALIGNMENT PROCEDURES 7.1 RECEIVER UNIT 1. Pre-selector and Post-selector Filters Both the pre-selector and post-selector filters have been pre-tuned at the factory, so no alignment is required. 2. FVR001/FVR002 Alignment FVR001 adjusts the squelch tight level FVR002 is used to set the voltage at TP001 to 2.5 Volts DC 3. VCO Alignment The VCO is pre-aligned at the factory to cover the full A or B sub-band. However, if you need to re-adjust the VCO following a repair, set the VCO control voltage at TBD to 10.5 Volts DC by adjusting the coil winding spacing of L303 at the high end of the sub band. 7.2 TRANSMITTER UNIT 1) FVR201 Alignment This potentiometer adjusts the transmit modulation level. Carefully align this potentiometer to obtain as flat of deviation response as possible from the lowest to the highest frequency supported by the transmitter. 2) FVR202 Alignment This potentiometer determines low frequency (below 300Hz) deviation. When either or all of POCSAG, CTCSS and DCS are used, it is necessary to adjust this pot to provide enough deviations at low modulation frequencies. 3) FVR203 Alignment This potentiometer adjusts the maximum transmit deviation. 4) FVR204 Alignment This potentiometer sets the transmitter maximum output power level. 5) VCO Alignment The VCO is pre-aligned at the factory to cover the full A or B sub-band. However, if you need to re-adjust the VCO following a repair, set the VCO control voltage at TBD to 10.5 Volts DC by adjusting the coil winding spacing of L303 at the high end of the sub band. 7.3 POWER AMPLIFIER UNIT 1) FVR501 Alignment This potentiometer is used to adjust the minimum reverse power detection point when the transmit antenna port is terminated with 50 ohm load. 2) FVR502 Alignment This potentiometer is used to set the threshold point for reverse power detection. 3) FVR503 Alignment This potentiometer is used to set the threshold for transmit low power alarm detection. 4) FVR504 Alignment This potentiometer is used to set the maximum transmit power level of the Power Amplifier Unit. Do not exceed 120 Watts or the radio’s FCC type acceptance, whichever is lower. 7.4 LOGIC UNIT 1) VR401 Alignment This is the digital pulse code rotary switch on the Front Panel Unit used to set the volume. 2) VR402 Alignment This is the digital pulse code rotary switch on the Front Panel used to set the squelch level. 3) FVR401 Alignment This potentiometer, located on the Front Panel Unit and accessible from the front of the radio assembly, is used to fine-adjust the Hi-Power Level of the transmitter. 4) FVR402 Alignment This potentiometer, located on the Front Panel Unit and accessible from the front of the radio assembly, is used to fine-adjust the Lo-Power Level of the transmitter. 7.5 DESCRIPTION OF CIRCUITS TO STABILIZE OUTPUT FREQUENCY The transmitter uses a TCVXO (Temperature Compensated Voltage Controlled Crystal Oscillator) to generate 12.00MHz reference frequency for the transmitter PLL and VCO circuit. The accuracy of the TCVXO is less than +/- 0.00015% over the range of –30 degree C to +60 degree C. 7.6 DESCRIPTION OF CIRCUIT TO SUPPRESS SPURIOUS EMMISSIONS AND LIMIT MODULATIONS A multiple pole Low Pass Filter is used after the final power amplifier stage within the Power Amplifier Unit. It is designed to sharply attenuate spurious and harmonics frequencies above the highest frequency in the sub-band of the radio. Modulation limiting is performed by Tx audio processor AK2344 located on the Logic Unit. Internal limiting/compression amplifier provides excellent limiting with minimum distortion. In addition to modulation limiting, this device contains all circuitry to perform pre-emphasis, band pass shaping and CTCSS encoder.

Both lines were observed with the DUT transmitting. The bandwidth of the spectrum analyzer was 10 kHz with an appropriate sweep speed. Bandwidth 20 dB: The measurements were made with the spectrum analyzer's resolution bandwidth (RBW) = 1 MHz and the video bandwidth (VBW) = 3 MHz and the span set as shown on plot. Power Output: The RF power output was measured at the antenna feed point using a peak power meter. Antenna Conducted Emissions: The RBW = 100 kHz, VBW = 300 kHz and the span set to 10.0 MHz and the spectrum was scanned from 30 MHz to the 10 th harmonic of the fundamental. Above 1 GHz the resolution bandwidth was 1 MHz and the VBW = 3 MHz and the span to 50 MHz. Radiation Interference: The test procedure used was ANSI/TIA 603-C:2004 using an Agilent spectrum receiver with pre-selector. The bandwidth (RBW) of the spectrum receiver was 100 kHz up to 1 GHz and 1 MHz above 1 GHz with an appropriate sweep speed. The VBW above 1 GHz was 3 MHz. The analyzer was calibrated in dB above a micro volt at the output of the antenna. Applicant: MIDLAND RADIO CORPORATION FCC ID: MMA7132…
